Cooling system. Flushing
Cooling performance is reduced by deposits in the
radiator and cooling channels. The cooling system
must therefore be flushed through when the coolant
is replaced.
1. Drain the coolant as above.
2. Insert a hose in the radiator filler opening and
rinse out with freshwater until the water which
runs out is completely clear.
3. Close the drain cock and plugs. Fill with new
coolant according to the instructions in the sec-
tion "Coolant. Checking and topping up"
Cooler (charge air cooler TAD). External
cleaning
Remove the required guards to access the radiator.
Clean with water and a mild cleaning agent. Use a
soft brush. Take care not to damage the cooling
vanes. Reinstall components
IMPORTANT! Do not use a high pressure
hose.
Coolant filter. Replace
The coolant filter is only standard on 16-litre en-
gines. For other engines, it is available as an option-
al extra. It has the task of filtering the coolant and
providing anti-corrosion protection.
IMPORTANT! To prevent overdoses of anti-
corrosion protection subsequently causing a
blockage, the filter should not be replaced at
the same time as the coolant, but 6 months af-
ter the first coolant replacement and then every
6 months.
Close the cocks (1) or turn the cock to position "A"
(16-litre). Remove the filter with a suitable filter
puller. Dampen the gasket and screw on new filter by
hand. Tighten by 1/2 turn once the gasket is tight.
Open the cocks (1) or turn the cock to position "B"
(16-litre).
